truck blowing whitish blue smoke (need help)

[txtonka6.0]

i'm a newb here so say hello. i have a problem that perhaps ya'll could help me with. i'm 21 and this is the first powerstroke i have owned. my dad owns a 02 7.3 4wd. my truck is a 05 crew cab 4wd 6.0 with 4 inchs of lift. the problem that i have is that my truck is losing power, studdering and blowing a whitish blue smoke out the tail pipe. it did once before and i changed my fuel filters and it stopped but today it did it again. it's only been like 2000 miles since i changed them the fuel filters. the truck only has 40,000 miles. any help would greatly be appreciated.

hellow txtonka, welcome to SDD.

i think blueish/white smoke is gonna be oil lose.

some others will chime in soon that really know, but i think that is right.

Headgaskets? White is going to be either unburnt fuel or coolant and blueish is defenitley oil.

i thought BLACK was unburnt fuel ? White is steam <water/coolant> &
blue is oil.

whens this "studdering" take place...under load ? or idling ?
do you have other (good) guages ? boost ? egt ? what are they doing...

is the boost guage jumping and falling off under steady acceleration ?

any engine codes ?

i know its not the FINAL answer, but your truck has a 100k/5yr warrenty
on it...so maybe once we diagnose it some more youll be able to make
a decision about taking it in or performing the repair yourself.

i guess we should also ask if youre running any kinda performance
enhancing "tuner" or "flip chip"

 

[patrickc]

Sorry bushpilot. I should have said whiteish/grey meaning an unburnt fuel and water mixture. Black is defenitly excess fuel.

Black is partially burnt fuel...white on a cold start is unburnt fuel or water if it's up to temp....blue is oil.

thanks guys i really appreciate the responses. my truck is all stock except for 4in. exhaust.
it studders as soon as i start it up. no the boost gauge isnt jumping around it stays steady. but like tonight i left the gym and i drove about 20 miles home and it was fine. it was running really good. i hit it hard a few times and it ran like normal. i havent had it plugged in so i dont know about codes yet. im going to get it plugged in tomorrow at work.
